What is "Acrylic" Paint?`
excap
I saw a gallon of "100 % Acrylic" that made no mention of being either Latex
or Oil based.
Is it a hybrid of the two?
And part 2 of this question:
I know you can't put oil based paint over previously painted latex paint but
what about acrylic? How does that figure in the mix?

Latex = acrylic

There is "oil based" and "water based". No latex in latex paint. What
you put over what depends largely on the substrate and gloss. Use the
right primer and prep. Latex on hard enamel is nasty, as the next paint
job will be more difficult beause you can't sand latex. Letex on
concrete is preferred because it breathes a bit, and concrete always has
moisture in it.

Speaking of enamel, that would be another good question. Is enamel a type of
paint? Basically, enamel just means "shiny".
Hopkins
oil primer first.
You can put oil on latex.
Hopkins
of paint, it's like latex...
latex = water-based
enamel = oil-based
Hopkins
product, read the label under 'clean up' or 'thinning'.

Beg to differ. You can buy water based enamels. The desktop
directly under this keyboard was painted with a water based
enamel paint. I didtinctly rememebr selecting enamal for it's
hard wearing finish. I also know that I cleaned up the brush
with water.

Maybe "usually", maybe not. There are water based enamels, that's why I
pointed it out.

Dang, as soon as I say that I check it out just to be sure. There are flat

MY ANNUAL EXPLANATION ABOUT "LATEX PAINT" BEING UNRELATED TO "LATEX
RUBBER".
The word "latex" in general and with regard to paint means "emulsion",
nothing more. The emulsion may be of acrylic, or other things like
polyvinyl acetate or natural casein. The term "latex paint" tells you
nothing but that the paint is a water-based emulsion. It does NOT tell
you what species of polymer.
"Natural latex", often confusingly just called "latex", is the rubber
tree sap, an emulsion of natural rubber. This has nothing to do with
"latex" paint. "Latex rubber" is rubber made from natural latex.
Before modern polymers, this was the only latex polymer, so in those
days "latex" almost always meant natural rubber emulsion, leading to a
misunderstanding today in peoples minds.
Many plants have latex sap, not just rubber trees.

If it's hard and glossy it's called "enamel" because the original enamel
was glass fused to metal. They sell latex "enamel" and it *is* glossy.
But hard? I don't think so...it isn't sandable, stuff sticks to it, it
doesn't flow.
There is no reason that there couldn't be a decent water based "enamel"
(may already exist) but it would use polyurethane. Latex is fine for
drywall and concrete, lousy for wood. Lousy, that is, if one cares
about how it looks.

OK, "acrylic" paints are acrylic latex but not all latex paints have
acrylic. Happy?

In oil paints at least, all start life as glossy. Adding a flatting
agent - talc, usually - in varying amounts is what changes the sheen.
Used to be that paint stores actually sold talc so you could mix
whatever sheen you wanted; nowadays, they don't even know what flatting
powder is.
Hopkins

Let me amend that...
I should have said that latex (or acrylic latex) is lousy for wood
*furniture*...tables, desks, cabinets...like that. There is no way
under the sun to get a good paint job on same with those paints. For
things like exterior trim, it is fine.

I'm no chemist but his post certainly seems accurate to me. Dang site
better than people thinking latex paint is made with rubber (even though
the miserable stuff sands as if it were).
LATEX
A milky-white, fine dispersion of a solid resin in an aqueous medium.
Also used to describe water-thinned paints, the principal vehicle of
which is latex.
LATEX PAINT #1
Paint containing colloidal binder particles formed by emulsion
polymerization. A common term for water-based and water-reducible
coatings.
EMULSION #1
Liquid droplets dispersed in another immiscible liquid.
EMULSION #2
A colloid in which both phases are liquids
LATEX PAINT #2
Water-based paint made with a synthetic binder (latex), such as acrylic,
vinyl acrylic, or styrene acrylic latex.
Richard J Kinch

"The formulation of an emulsion paint consists basically of combining
pigment and latex. The term latex originally meant the milky juice of
certain plants, but has been adopted by the industry to denote a suspension
of polymer particles in water."
